[Bug 1217229] [NEW] Laggy & Finally Completely Frozen 12.04.2 on Large cp or rsync

 

Public bug reported:

I have two pairs of raided disks.  I am trying to copy 1/2 T of data
from one to the other.  First I tried "cp /from /to".  It seemed to
behave ok, so I left it overnight.  When I came back in the AM, the
machine was completely frozen.  I had to use the power switch.  Only
about 150GB had been copied.  I tried again with "nice -n 10 cp ..." and
the same thing happened.  Then I discovered ionice and shifted to rsync.
So I used "ionize -n 7 rsync -cva /from /to".  I also turned off the
sleep/lock for the display.  Again it seemed to behave ok, so I left it
while I went for dinner.  Two-three hours later, I found that all
windows were frozen.  I couldn't use REISUB, the reset switch _or_ the
power switch.  I had to power off using the switch on the power supply.
Rebooting, I found that about 300G had been copied by this point.  I am
trying for the 4th time now, again using rsync.  iotop is running.  It
regularly freezes between rsync's copying one file and the next.  If I
try to shift to a window or type at the terminal, there is a freeze
until the file being copied by rsync is finished.  If I keep typing at
the terminal (or in the text-box in Firefox, as I am now) then things
become smooth until I stop for a bit.    Then the freezing begins to
happen again.  (That's not completely true.  Tab completion at the
terminal is a disaster.  Cut & paste in this window is the same.)  It
may be my fantasy, but it seems that if I keep using the machine,
getting it to respond to keyboard/mouse intput, then it doesn't
permanently freeze up.  It's when I leave to it's own devices for some
time that I have a problem.

The only difference between the last try and the first 3, is that after
having a look at dmesg, I enabled IOMMU in the BIOS.  Probably
irrelevant, but I did also notice the "spurious 8259A interrupt: IRQ7"
message in dmesg that has been reported in bug #75626.

I haven't changed anyting with the I/O scheduler, which has been
reported as causing I/O problems in bug# 427210 and #131094.  So, it
still reads: "noop [deadline] cfq"

Tyan S3970 with 2 CPU's (8 cores).
Two pairs of WD drives (500G & 2T)
TARO add-on storage card (used by the 2T drives)
Ubuntu 12.04.3 fully updated.  
Essentially new install (During this process I only added iotop, atop, htop, acpi, m5deep & emacs)
500G drives are RAID-1; 2T drives are RAID-1 & encrypted.
